1. An apparatus for creating a unique event notification, comprising:

  • a memory;

    an object accessor configured to access an object that represents hardware;

    a notification value accessor configured to access a notification value;

    a universally unique identifier (UUID) accessor configured to access a UUID that is generated by a computer system that the apparatus is associated with;

    a unique action designator configured to compute a unique action designation based on the notification value and the UUID, wherein firmware is enabled to request that an operating system perform a unique action determined based on the unique action designation and wherein the firmware and the operating system are associated with the computer system;

    an action performer configured to perform the unique action on the hardware, wherein the unique action is determined based on the unique action designation;

    wherein;

    an event notification interface creates an event notification that includes a reference to the object, the notification value, and the UUID;
